The building structure moves downwardly in response to water leaving the building structure container.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to buildings and, more particularly, to buildings designed to be resistant to floodwaters.

2. Description of the Related Art

Particular geographical areas are known to suffer from flooding, which is usually seasonal in nature. For example, in the United States, the gulf coast states during the hurricane season are prone to hurricane flooding. The damage to buildings from flooding and high winds is costly and it is inconvenient and time consuming to rebuild. Further, people who are caught in a flood often wait for long periods of time before being rescued, but need access to food and shelter in the meantime.

To reduce flood damage, people have resorted to building many different types of flood protection structures to divert the floodwaters away from buildings. These flood protection structures include dams, floodwalls, dikes and levees, among others. However, flood protection structures are expensive and can fail in certain circumstances.

Some solutions to this problem involve modifying the building susceptible to flooding. For example, when a building site is chosen near a body of water susceptible to flooding, construction techniques often involve the placement of several fixed piers or pilings under the building so that it has a raised building foundation. These fixed piers permanently elevate the building to a predetermined height above ground level. This allows for a predetermined degree of floodwater to pass under the building without flooding it. However, it is often inconvenient to enter and exit the building because it is permanently raised.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 and 2 are top front and back perspective views, respectively, of a flood resistant structure 100, in accordance with the invention. Flood resistant structure 100 includes a building structure 101 positioned on a buoyant material structure (FIG. 4), wherein building structure 101 and the buoyant material structure are both carried by a building structure container 102. In accordance with the invention, the buoyant material structure floats in response to container 102 containing enough water therein. The water can be provided by many different sources, but it is generally provided by floodwaters, such as those from rain, a storm surge, an overflowing river, etc. In this way, building structure 101 is moveable in response to water entering and leaving container 102.

The water can enter building structure container 102 in many different ways. In accordance with the invention, the water enters through a fluid conduit connected to container 102 at one end. The other end of the fluid conduit is positioned away from building structure container 102 so that water enters container 102 before it rises to the level of building structure 101. In this way, the buoyant material structure, as well as building structure 101, are moved upwardly and floating before the water reaches the level of building structure 101. This reduces the likelihood that building structure 101 will be damaged by the floodwaters and also provides better protection for the people and valuables in structure 101. This feature will be discussed in more detail below.

FIG. 3 is a top perspective view of building structure container 102, in accordance with the invention. In this embodiment, building structure container 102 includes bottom wall 119 and sidewalls 112 a, 112 b, 112 c and 112 d which bound an inner region 113. Container 102 also includes an overhang 117 extending outwardly from an upper edge of walls 112 a-112 d. Here, overhang 117 is shown as extending horizontally, but it should be noted that it can extend in many other directions. For example, it can be sloped downwardly towards inner region 113. Container 102 can be made of many different materials, such as cement, and is formed so it holds water in inner region 113. It should be noted that inner region 113 extends up to the level of overhang 117.

In accordance with the invention, a fluid conduit 111 extends through building structure container 102 so that inner region 113 is in fluid communication with an outer region 114. Outer region 114 is outside of container 102 so it is not bounded by bottom wall 119 and sidewalls 112 a, 112 b, 112 c and 112 d. Outer region 114 can include regions above and/or below a ground surface (not shown), but it does not include inner region 113. Fluid conduit 111 includes an end 121 (FIG. 9) positioned within inner region 113 and an opposed end 122 positioned within outer region 114. In this way, inner and outer regions 113 and 114 are in fluid communication with each other through conduit 111. As discussed above, conduit 111 allows container 102 to receive floodwaters as the floodwaters approach building structure 101. In this way, the floodwaters enter inner region 113 through conduit 111 before the floodwaters flow over overhang 117. Fluid conduit 111 can be of many different types, such as a plastic or cement pipe.

In this particular example, fluid conduit 111 extends through sidewall 112 a for illustrative purposes, but it should be noted that it can extend through the other sidewalls of container 102. Further, one fluid conduit is shown here for illustrative purposes, but there is generally one or more fluid conduits which provide fluid communication between inner and outer regions 113 and 114. The fluid conduits extend in different directions away from container 102 to account for floodwaters approaching building structure 101 from different directions. It is useful if a fluid conduit extends in a direction towards a flooding source, such as a body of water.

In this embodiment, buoyant material structure 103 and building structure 101 are moveable along guide beams in response to water entering and leaving container 102. The guide beams are used to reduce the likelihood of buoyant material structure 103 and/or building structure 101 undesirably contacting sidewalls 112 a-112 d. Here, there are four guide beams, denoted as 110 a, 110 b, 110 c and 110 d, although there can be fewer or more guide beams in other examples. For example, some embodiments do not include guide beams, and others include one, two or five.

Guide beams 110 a-110 d extend upwardly from bottom surface 119 of container 102 and are secured to surface 119 with corresponding foundations 116 a, 116 b, 116 c and 116 d. Guide beams 110 a-110 d can have many different lengths, but they generally have lengths in a range from fifteen feet to thirty feet. In this embodiment, the guide beams are each about twenty two feet in length. The length of a guide beam is that between its opposed ends, although it can be the distance between its foundation and the distal end away from the foundation.

It should be noted that the guide beams can extend through building structure 101 in many different ways. In one embodiment, building structure 101 includes guide boxes, each of which receives a corresponding guide beam. FIG. 15 is a perspective view of guide beam 110 a extending through a guide box 130. In accordance with the invention, guide beam 110 a moves through guide box 130 as building structure 101 moves in response to water entering and leaving container 102. Guide boxes are useful to distribute, along the guide beam, a force transverse to it. In this way, building structure 101 is held more securely by the guide beams and is less likely to contact container 102. The guide beams can be solid or hollow beams, as shown in FIG. 15 wherein guide beam 110 a has an opening 131 extending through it.

FIG. 4 is a top perspective view of buoyant material structure 103, in accordance with the invention, being positioned in building structure container 102. As seen, buoyant material structure 103 includes openings for receiving guide beams 110 a-110 d. In this embodiment, buoyant material structure 103 includes buoyant material pieces 103 a and 103 b, although it generally includes one or more pieces. Buoyant material pieces 103 a and 103 b can include many different buoyant materials, such as foam, and can be attached together if desired. Pieces 103 a and 103 b can be attached together in many different ways, such as with an adhesive and fasteners.

FIG. 5 is a top perspective view of a building foundation 104 being positioned on buoyant material piece 103 b. In this embodiment, building foundation 101 includes openings for guide beams 110 a-110 d to slide through. It should be noted that foundation 101 can be of many different types. In this embodiment, it is a single piece of material, such as wood, having openings extending therethrough for receiving guide beams 110 a-110 d. However, foundation 101 generally includes one or more pieces, which can be formed before or after they are positioned on piece 103 b. For example, in some embodiments, building foundation 104 includes concrete positioned so it hardens on buoyant material structure 103. It should be noted that guide boxes, such as guide box 130 of FIG. 15, is generally carried by foundation 104, but it is not shown here for simplicity.

FIG. 6 is a top perspective view of a building frame structure 105 being positioned on building foundation 104. Building frame structure 105 defines the first floor of building structure 101. In this embodiment, building frame structure 105 includes walls connected together to form rooms for building structure 101. In this embodiment, building frame structure 105 is shown as being a single piece, but it generally includes one or more pieces connected together. It should be noted that in other embodiments, building frame structure 105 can be fabricated on building foundation 101 or it can be fabricated beforehand.

FIG. 7 is a top perspective view of a building frame structure 106 being positioned on building frame structure 105. Building frame structure 106 defines the second floor of building structure 101. In this embodiment, building frame structure 106 includes walls connected together to form rooms for building structure 101. In this embodiment, building frame structure 106 is shown as being a single piece, but it generally includes one or more pieces connected together. It should be noted that in other embodiments, building frame structure 106 can be fabricated on building frame structure 105 or it can be formed beforehand.

FIG. 8 is a top perspective view of a building roof structure 108 being positioned on building frame structure 106. Building roof structure 108 defines the roof for building floor structure 107. In this embodiment, building roof structure 108 includes pieces connected together to form a roof for building structure 101. In this embodiment, building roof structure 108 is shown as being a single piece, but it generally includes one or more pieces connected together. It should be noted that in other embodiments, building roof structure 108 can be fabricated on building roof structure 106 or it can be formed beforehand.

FIG. 9 is a partial side view of container 102 and fluid conduit 111, in accordance with the invention. In this embodiment, building structure container 102 is positioned so it extends into the ground and overhang 117 is level with a ground surface 126. In this way, water near a region 129 will flow into inner region 113 when it reaches overhang 117. Region 129 is a region near where container 102 engages the ground near ground surface 126. Fluid conduit 111 extends from a region of container 102 near bottom surface 119 and upwardly towards ground surface 126. Fluid conduit 111 extends from side 112 a so that end 121 is within region 113 and end 122 extends through surface 126 about a distance d₁ away from side 112 a. In this way, a region 114 a is between conduit 111 and surface 126 and a portion 114 b is below conduit 111.

Distance d₁ can have many different values. In this embodiment, distance d₁ is about thirty feet, although it can be more or less than this value. Distance d₁ is generally chosen to ensure that enough water enters container 102 so that buoyant material structure 103 is floating before the water flows through region 129 and into inner region 113. In this way, distance d₁ is chosen to ensure that enough water enters container 102 so that buoyant material structure 103 is floating before the water flows over overhang 117 and into inner region 113. As distance d₁ increases, the time between when buoyant material structure 103 is floating and the floodwaters reach region 129 increases. As distance d₁ decreases, the time between when buoyant material structure 103 is floating and the floodwaters reach region 129 decreases.

FIG. 10 is a partial side view of container 102 and fluid conduit 111, in accordance with the invention, wherein overhang 117 extends above ground surface 126. In this embodiment, building structure container 102 is positioned so it extends into the ground and overhang 117 is a distance L₁ above ground surface 126. In this way, water near building container 102 will need to rise up distance L₁ before it can flow over overhang 117 and into container 102.

In this example, fluid conduit 111 extends from side 112 a so that end 121 is within region 113 and end 122 extends through surface 126. A portion 111 a of conduit 111 extends from a region of container 102 near bottom surface 119 and outwardly from sidewall 112. A portion 111 b of conduit 111 extends from portion 111 a at a turn 111 c and upwardly towards ground surface 126.

FIG. 11 is a partial side view of container 102 and fluid conduit 111, as shown in FIG. 9, with buoyant material structure 103 extending through inner region 113 and carrying building structure 101. Here, floodwaters 127 flows towards container 102 on ground surface 126. A portion of floodwaters 127, denoted as floodwaters 128, flows on ground surface 126 past end 122 and a portion of floodwaters, denoted as floodwaters 129, flows through end 122 and into fluid conduit 111.

In accordance with the invention, floodwaters 129 flows through conduit 111 towards end 121 where it enters container 102. When enough of floodwaters 129 enters container 102, buoyant material structure 103 moves upwardly so that foundation 104 moves to a level above ground surface 126, as shown in FIG. 12. As discussed above, buoyant material structure 103 and building structure 101 move relative to guide beam 110 a. Foundation 104 is at a distance L₂ above overhang 117 when the water level in inner region 113 reaches ground level 126. Buoyant material structure 103 is moved upwardly so that it is a distance L₃ from bottom surface 119. For the embodiment shown in FIG. 10, floodwaters 128 will not flow over overhang 117 until the floodwaters rise up distance L₁. Inner region 113 fills up with water before floodwaters 129 reaches overhang 117.

In this way, foundation 104 is moved to a position above the floodwaters as the floodwaters approach building structure 102. Foundation 104 is kept above the floodwaters, which reduces the likelihood of building structure 101 suffering from water damage. This also decreases the likelihood of occupants of building structure 101 being injured and provides better protection for the property included therein.

FIG. 13 is a partial side view of container 102 and fluid conduit 111, as shown in FIG. 9, with a pump 118 in fluid communication with inner region 113. Pump 118 is used to pump out water contained by container 102. It is useful to do this after the floodwaters have receded and it is desirable to lower building structure 101. Hence, pump 118 and fluid conduit 111 operate as a drain for container 102.

In this embodiment, a fluid conduit 118 a has one end connected to an input of pump 118 and an end 118 c within inner region 113. A fluid conduit 118 b has one end connected to an output of pump 118 and another end (not shown) positioned away from container 102. The end of fluid conduit 118 b away from container 102 can be positioned at many different locations, but in this example, it is positioned at the other side of opposed end 122 of fluid conduit 111. It should be noted that pump 118 is carried on ground surface 126, but it can be positioned at many other locations, as will be discussed presently.

FIG. 14 is a partial side view of container 102 and fluid conduit 111, as shown in FIG. 9, with pump 118 in fluid communication with inner region 113 and positioned within outer region 114 and below ground surface 126. In this embodiment, fluid conduit 118 a has end 118 c within inner volume 113 and extends through sidewall 112 a and away from container 102 where it is connected to the input of pump 118, as described above. End 118 c can be moved from sealed and unsealed conditions. End 118 c is generally sealed when it is desired for container 102 to contain water. End 118 c is unsealed when it is desired to remove water from container 102. Fluid conduit 118 b is connected to the output of pump 118 and extends away from container 102. It should be noted that fluid conduits 118 a and 118 b extend below surface 126 in this example, but they can extend above it too, if desired. Further, pump 118 can be at or above surface 126, as discussed above.
